The actress – who rose to fame alongside twin sister Tia Mowry in the 1990s sitcom – announced her baby news via Instagram.
Tamera proudly displayed her positive pregnancy test for all to see alongside the caption: "Can't wait to meet baby number two!"
Like other celebrities such as Danielle Jonas, the actress announced her pregnancy via a sponsored post with ClearBlue. (Hence the pregnancy test in the photo!) She's a spokesperson for the brand.
Tamera and husband Adam Housley are already parents to son Aden, two.
The 36-year-old actress rose to fame as a teenager on Sister Sister, and later starred alongside Tia in their own reality show. Now, she is the host of The Real talk show in the US alongside the likes of Adrienne Bailon.
Her husband Adam is a correspondent for Fox News.
Congrats to the happy couple!
